OIL SAVER.

Application led September 26, 1918. Serial No. 255,766.

To all whom, t may cof/wem:

Be it known that I, CHARLES M. HEETR,

" a citizen' of the United States, residing at ful Improvement in OilSavers, of which the. full, clear, and exact descrip.

Butler, in the county of Butler and State of Pennsylvania, .haveinvented a new and usefollowing is a tion, reference being had to theaccompanying drawings, forming part of this specification, in which-'- tFigure 1 is a side elevation of one form .of

my improved saver in connection with a.

supporting device therefor.

Figure 2 is a plan View of Figure 1. Figure 3 is a sectional view on theline III-III of Figure 2. Figure 4 is a sectional view on the lineIVd-IV of Figure 3 with lthe tubing omitted, an

Fixgure `5 is a sectional view on'the line V- of Figure 4 with theparts'in their open positions.

a Greater amount of friction to that portion of the tubing extendingfromthesaver to the well than to that portion of the tubingV extendingfrom the saver to thepulling device, so that when the upper portion isrotated to-Ydisconnect the same from the por- 455 designates tion withinthe well, said portion that is rotated will readily slip within thesaver while the other portion will be fixedly held against rotation andprevented from slipping out of the oil saver.

The precise nature of" my invention will be best understood by referenceto the yaccompanying drawings which will now be described, it beingpremised however, various changes may be made inthe details ofconstruction and the general arrangement ofthe parts without departingvfrom the spirit and scope of my invention as defined in the appendedclaims. l

In the drawings the reference character 2 the oil saver which issupported bymeans of the flexible device 3 fromthe that end 0f the jibcrane 4. This'jii is rotatably supported on a standard 5. 6 designates aportion of the tubing extending from the4 saver into the well casing,and 7 designates Athat portion of the tubing extending from the saver tothe tubing pulling device'.v

The saver 2 comprises two half sections 8, which are hinged to eachother by means of lugs having a hinge pin extending therethrough. 9 isprovided with an eye.10 to which the exible connection' is connected.-Each of the sections 8 is provided with a recess 11 at thetop thereof,as well as a recess 12 in the lower end thereof. Seated within therecesses 11 and 12 of each section are similar vsemi-cylindrical packingrings or members The upper end ofthe .hinge pin` 13 and 14,v the widthof the vpacking rings l 13 being very much less than the width of thepacking rings 14 in the direction of the axis of the saver. One of thesections 8 of thecasing is provided with longitudinal recesses 15, whichextend from the recess 11 to the recess 12, and seated within theserecesses. 15 are iexible packing members 16.

One of the sections 8 of the casing is prolvided with an outlet `17,between the packing members 13 and 14, to which is connected a flexiblehose 18 for conveying the oil to any suitable source; .Pivotallyconnected to one of the sections 8 of the casing,

is a locking lever 19 having a recess 20 therein for engaging a camprojection 21 on the other section l8 of the casing for clamping thecasing about the tubing to be drawn.

The operation of the device is as follows: The tubing is raised by meansof the usual elevatorto bring a coupling member, such `as 22, to theposition shown in Figures 1 the well casing 25 and 3, and supported onby means of another elevator 26. The casing 2 is then securely clampedabout the coupling member 22 and the the tubing. When the casing 2 isclamped in position, the packing member 13 will form atight joint aboutthe portion 7 of the tubing, whilel the packing members 14 will formatight joint about 'the coupling member 22, and at the same time thepackbeween the packing members 13 and 14. The portion 7 can'then befreely rotated to disconnect it from the coupling member 22 as thefrictional engagement between the portion 7 and the packing 13 is verymuch portion 7 of l members 16 w1ll prevent any leakage less .than thefrictionalengagement between the oil saver is opened and swung to theposition shown in dotted lines in Figure 2, the pulling device is thenconnected to the elevator 26, below the coupling 22.` The tubing is thenraised to bring the next coupling vmember 22 to be disconnected to itsproper position with relation 'to the'saver,wh1ch is again clamped aboutthe tubing as before described.

The' advantages of my invention lresult from lthe provision of an oilIsaver having separable sections, so arranged that a greater amount offriction will be -created between the packing members which engage thelower portion of the tubing, than that between the upper packing membersand the tubing whereby the `portion of the tubing,

vbelow the oil saver is rigidly held against rotation while the upperportion can be readily rotated lto uncouple the tubing and also topermit the upper portion to be moved relatively to the 'lower portion todrain the oil therefrom. Also from the provision of a saver whose lo-werpacking members are of greater area thanthe upper packing members,whereby' the lower portion ofthe well casing or tubing will be heldagainst rotation when the upperl portion is rotated to uncouple thesame.

. Still a further advantage of my invention results from `an improvedmeans for sup` porting the saver at a predetermined point above themounting level, which means is sol arranged that the saver can readilybe swung into operative position with relation vto the well tubing to bedrawn.

I claim:

1. An oil saver having a plurality of separable sections, packingmembers in each end of said sections adapted to engage casing portionsof different diameters, theA width of the contacting surfaces of thepacking members at one end of the saver being materially greater thanthe widthr of the contacting surfaces of the packing niembers at theother end of the saver, said packing members of greater width beingeffective for preventing rotation of the portion of the casing engagedthereby during rotation of the portion of the casing engaged by theother packing members, and means for locking said sections about thecasing to be drawn. f

2. As an article of manufacture, a sectional oil saver having packingmembers in the opposite ends thereof, said packing members in one end ofthe saver having a width at least twice that of the packing members inthe other end of the saver, whereby a greater clamping action is eXertedadjacent oneI end of the saver` than the other, the clamping actionexerted by the members of greater width being effective .for preventingrotation of the portion of the casing engaged thereby during rotation ofthe portion of the casing engaged by the members of lesser width,substantially as described.

In testimony whereof, I have hereunto set my hand.

' CHARLES M. HEETER.
